The purpose of this experiment is to learn about drag force, the coefficient of drag and terminal velocity. In Study 1 you will use Dimensional Analysis to determine a functional form for the drag Force . In Study 2 you will use Data to confirm the velocity dependence of the drag Force. In Study 3 you will study terminal velocity and use a graph to determine the coefficient of drag for several unknown shapes. In Study 4 the terminal velocity for a sky diver is calculated. Topics: Drag Force, dimensional analysis, terminal velocity, shapes

Physical units are also known as dimensions in physics. Since the quantities represented by the two sides of an equation must have the same dimensions, it is often possible to arrive at the form of an expression connecting physical quantities by the consideration only of the dimensions of the quantities involved, without a detailed theory.

This is an in class experiment at a Physics 100 level to teach about the drag force and terminal velocity. In Study 1 you will use Dimensional Analysis to determine a functional form for the drag Force. In Study 2 you will use Data to confirm the velocity dependence of the drag Force. In Study 3 you will study terminal velocity and use a graph to determine the coefficient of drag for several unknown shapes. In Study 4 the terminal velocity for a sky diver is calculated and for the RAF Grand... Topics: Drag Force, Coefficient of Drag, Terminal Velocity, Dimensional Analysis, skydiver, Grand Slam bomb

In the Second Part of this Three Part Introduction to Dimensional Analysis, we shall analyze three physical systems. We shall derive Kepler's Third Law, the expression for the frequency of a Helmholtz Resonator, and the period of a suspended dipole magnet oscillating in a magnet field using dimensional analysis. Topics: dimensional analysis, Kepler's Third Law, the frequency of a Helmholtz Resonator, period of an...
